BNSF Railway's H-BARSDG1-21 freight, heading from Barstow to San Diego, passes through the city of Orange, California, on May 21st, 2016. This line normally sees freight action at night, when Amtrak and Metrolink trains are not running. But due to overnight track work, the BNSF's H-BARSDG and H-SDGBAR both operated during daylight hours on this day. Heading south on Track 1 are BNSF ES44DCs 7728, 7759, 7736 and 7717.
